SPECIFICATION forming part of Letters Patent No. 582,647, dated May 18,1897.

Serial N0. 626,442. (No model.)

To aZZ whom it may concern:

Be it known that I, NELSON D. IIOSLEY, a citizen of the United States,residing at Meriden, in the county of New Haven and State ofConnecticut, have invented anew and useful Attachable Pedal forCombination-Pianos and Similar Instruments, of which the following,together with the accompanying drawings, is a specification sufficientlyfull, clear,

IO and exact to enable persons skilled in the art to which thisinvention appertains to make and use the same.

This invention is more especially designed for the blow-pedals to beattached to pianos I 5 when pneumatic or automatic playing mechanism andwind-inducing bellows are applied thereto; but said invention is alsoapplicable and may be employed for organs, combination instruments, orother instruments of similar kinds in which pedal mechanism is required.

One part of my invention relates to the construction and combination ofmeans for supporting and attaching the pedal base or frame to the frontof the piano-case, the objects being to provide an attachable pedalmechanism that can be applied to piano-cases without cutting awayportions of the case; also, to render the pedal-base readily removableand replaceable when desired, and to provide a convenient interlockingjoint therefor, and, further, to render the attachment adjustable, sothat the pedal-base will rest securely and firmly when used upon a bare3 5 floor or with any desired thickness of rug or carpet beneath saidpedal-base.

Another part of my invention relates to the novel construction of thepedal-levers and their arrangement in a manner that will per- 0 mit ofthe levers being folded back and the pedal laid flat, or substantiallyso, upon its base, the end of the pedal locking or supporting the partsin non-operative position, the object being to provide a pedal mechanism4 5 that can readily and conveniently be ad j usted when idle to suchpositions as will not materially encumber the fore space or in any wayinterfere with the free access to and use of the regular piano-pedalswhen the piano is used for ordinary practice, or without operatin g theautomatic action and blowing appliances; also, to confine thepedal-levers, together with the bellows, at a fixed position and incompact order when not required for use. The particular subjectmatterclaimed is hereinafter definitely specified.

In the drawings, Figure 1 is a plan view of pedal mechanism embodying myinvention. Fig. 2 is a side view showing the parts in operativeposition, also by dotted lines indicat- 6o ing the action movement. Fig.3 is a section view showing the parts as adjusted to nonoperativeposition. Fig. & shows the detail of the attaching devices for thepedal-base. Fig. 5 shows the roller-arm separately by a rear view andsection, and Fig. 6 shows the swing-lever separately by rear view andside view.

Referring to parts, A indicates the lower portion of a piano-case frontsupporting the usual piano-pedals a a, and B indicates an exhauster orbellows arranged within or at the rear of the instrument-case forinducing the air-currents that operate the pneumatic action, motor, ororgan-reeds, (not herein shown, but which may be of any desired orwell-known arrangement,) and for the operation of which bellows myimproved pedal mechanism is intended.

C indicates the pedal-base, consisting of a connecting-strip with twoforwardly-extending portions to which the pedals or foot-plates E arehinged at c. This base is provided at its rear edge with earpieces D,rigidly fixed thereon, each having an upward transverse S5 flange 3 atits rear end and a downward forwardly-hooked lug 5 beneath. (See Fig.

A set-screw F is arranged through the flange near its upper edge, asindicated.

For attachment to the piano I provide an 0 angle-plate G, that fits thebottom front angle of the case A without cutting thereinto, but to befirmly secured thereto by screws. Said angle-plate has a projection orflange with a hole 7 therein for receiving the hooked lug 5, 5 whichlatter is inserted and hooked under the fore edge of the flange, thusaffording a detachable interlocking joint for the pedalbase. Theset-screw F when turned in until its end bears against the front of theangleplate confines the parts in place.

I indicates a swing lever or arm, the upper end or head of which ispivotally supported at i in connection with the ears of a hingingpieceor fulcrum-plate K, that is seated flat upon the front surface of thepiano-case A and secured thereto by screws. The lower part of saidswing-lever is formed with a backward-curved extension I, its end forkedor fitted for pivotal connection at S with the eouplin g rod or bar L,that passes beneath the body of the instrument and connects said lever Iwith the bellows-exhauster.

J indicates an arm carrying at its bifurcated upper end a roller on,while its lower end, which is also bifurcated, is backwardly offset andpivoted at 9 to the swing-lever I. The crotch 10 of arm J is fitted toshoulder or seat against the heel 12 of lever I when said roller-arm isswung down to its normal working position, as in Fig. 2, and to theretake firm support for moving with the lever I as the latter swings onits pivot i, the two parts I and J together forming an anchor shapedswinging connection between the pedal E and rod L. The pedal rests uponthe roller on, its under surface being fitted with a runway for saidroll, and preferably surfaced with felt n. hen the pedal is depressed,it forces the roll m and arm J downward and swings back the lever I andthrough the coupling-rod L operates the bellows. (See dotted lines onFig. 2.) The levers and pedal are raised by the action of thereturnspring (not shown) on the bellows-exhauster exerting its force inusual manner. An opening 0 is formed through the pedal-base for the playof the levers I and J, as indicated.

The front edge of the pedal-base rests upon the floor and thus affords afirm support beneath the hinging-points of the pedals, and the relationof this front edge of the base to the height of the attaching-angle Gcan be varied, still preserving its degree of firmness, by means of thethumb-screws F turned in to a greater or less extent, so as toaccommodate the degree of inclination or level that the base assumes,either resting upon the floor or upon a carpet or rug of greater or lessthickness laid beneath its front edge, or for adjustment to piano-casesof different heights from the floor. The base 0 can be detached at anytime by simply loosening the screw F and unhookin g the lugs 5 from theangleplates.

For adjusting the mechanism to its nonoperative position the roller-armJ is turned up against the front of the swing-lever I, and thepedal-plate is then pressed down close upon the base 0. The end of thepedal then rests against the front of the levers and there retains orlocks the parts in position, as shown in Fig. 3, a position of non-usewhere the levers and pedals E are out of the way from interfering withfree access to the pianopedals a when it is desired to use theinstrument manually and without using its automatic action or blow-pedalmechanism.

In Fig. l the pedal at the left is shown in normal position for use,while the pedal at the right is shown as laid down in non-operativeposition. If desired, a block .5' may be fixed to the under side of thepedal to support it otherwise slightly clear from the base when at itsnon-operative position.

I claim and desire to secure by Letters Iatent a 1. In combination witha piano-case and an attachable pedal mechanism, the fulcrumplate seatingflat upon the exterior surface of the case, and the an gle-plate fittingthe corner of the case, without cutting thereinto, said plates providedwith projections for receiving the levers and base of the pedalmechanism for connection therewith relatively, as set forth.

2. In a pedal attachment for automatic pianos, the combination of afolding pedal-lever, a pedal unattached to said lever, and a pedal-basefor supporting said pedal couneeted with the piano-case by a detachableinterlock connection, substantially as set forth.

In an attachable pedal mechanism for purposes set forth, the pedal-baseprovided with earpieces each having at its end an upward flange and ahooked lug beneath; in combination with angle-plates secured to thelower corner of the case and having a perforated projection for thereception of said hooked lugs, and the set-screws threaded in saidearpiece-flanges to bear against said angle-plate, substantially as setforth.

4:. The combination with the bellows coupling-bar, and the swingingpedal-plate of the swing-lever pivoted at its upper end, its lower endbackwardly extended and connecting with said coupling-bar, thefulcrum-plate supporting the pivot of said lever, the rollerarm pivotedto said swing-lever and carrying at its end a roll that underlies saidpedalplate; the crotch of said roller-arm adapted to seat against theheel of said swing-lever when down, and said arm adapted to fold up atthe front of said swing-lever allowing the pedal-plate to drop in frontof the same, substantially as set forth.

5. The combination of the pedal-base, the

IIO

10 carrying the pedal-hinges, and having the openings or recesses O, incombination with the pedals, swing-levers and attaching devices,snbstantially as set forth.

Vitness my hand this 4th day of March, 1897.
